Hyperswitch, developed by Juspay, is an open-source, highly scalable payment orchestration platform designed to simplify and streamline the complexities of integrating with multiple Payment Service Providers (PSPs) and payment methods. It aims to reduce integration time, improve success rates, and provide greater control over the payment flow for businesses. Unlike traditional payment gateways that often lock merchants into a single provider, Hyperswitch acts as a central hub, intelligently routing transactions to the optimal PSP based on factors like cost, success rates, and geographical location.

At its core, Hyperswitch is built around a flexible and extensible architecture. It utilizes a "connector" based system, where each PSP is encapsulated within a dedicated connector. This modular design allows for easy addition of new PSPs without impacting the core platform. The platform supports a wide range of payment methods including cards, net banking, UPI, wallets, and Buy Now Pay Later (BNPL) options. It’s written primarily in Go, leveraging its concurrency features for high performance and scalability, and uses PostgreSQL as its primary database. Key components include a transaction management service, a risk engine, a reporting and analytics dashboard, and a robust API for integration.

A significant feature of Hyperswitch is its intelligent routing capabilities. It employs a rule-based engine that allows merchants to define custom routing strategies. These strategies can be based on various parameters such as transaction amount, currency, card type, country, and even real-time PSP performance data. This dynamic routing ensures that transactions are always sent through the most reliable and cost-effective path, maximizing success rates and minimizing fees. Furthermore, Hyperswitch provides features like automatic retries, fallback mechanisms, and smart transaction splitting to further enhance resilience and optimize performance.

The repository provides comprehensive documentation, including guides for installation, configuration, and integration. It also includes a set of pre-built connectors for popular PSPs in India, such as Razorpay, PayU, and Cashfree, making it easier for businesses operating in that region to get started. The project is actively maintained by Juspay and has a growing community of contributors. The open-source nature of Hyperswitch allows businesses to customize the platform to meet their specific needs and integrate it seamlessly into their existing infrastructure.

Beyond core payment processing, Hyperswitch offers features for fraud detection and risk management. The integrated risk engine allows merchants to define custom rules and thresholds to identify and prevent fraudulent transactions. The platform also provides detailed reporting and analytics, giving merchants valuable insights into their payment performance. Ultimately, Hyperswitch aims to empower businesses with a powerful and flexible payment orchestration solution, reducing their reliance on single PSPs and enabling them to optimize their payment strategy for growth and efficiency.
